Application filed February 24,1906. Serial No. 302,819.

To all whom it may concern: 7

Be it known that I, CONRAD MILLER, a

citizen of the United States, residing at the: city and county of'Denver and State of: Colorado, have invented certain new and use- I fulImprovements in Dumping- Vehicles; and I do declare the=followingto be afull,v clear, and exact description'of the invention, such as willenable others skilled in the art i to which it appertains to make anduse the:

same, reference being had to the accompany- I r the dumping positionFig. 4 is an elevation ing drawings, and to the figures ofreferencemarked thereon,- which form a part of this? specification.

My invention relates to improvementsin dumping vehicles.

My improvements are moreadapted for use in connection with wagons. Myobject isto provide a comparatively simple construction of this classwhich may be quickly and easily manipulated for dumping purposes Asshown 1n the drawing and hereinafter described, the vehlcle is providedwith two hinge members. the samebe-ing located onopposite sides of .thecentral portion of the vehicle, in which central portion is. located adumping platform which may be tilted, to:

dump in either direction asthe contents of the. end members aredischarged thereon.

My improvements also include means whereby the central dumping section.which preferably consists of two centrally hinged. parts, may be causedto fold downwardly thus discharging part of the load inv front and theother part in the rear of the central i part of the vehicle.

The construction is such that the operator can perform the entiredumping act by ma-g nipulating a lever located within convenient reachof the drivers seat constructed in the;

forward end ofthe vehicle.

It will be understood that my improved dumping construction may beemployed tof advantage with any material-which it may be desired to haulabout from place to place and discharged in bulk from the wagon body.

Having briefly outlined my improved con struction as well as thefunction it is'intended to perform, I will proceed to describe the samein detail reference being made to especially "lating chain. Fig. 9 butviewed at right angles thereto.

'Fig. 11 is similar to Fig. 9 but with the view of the same, the frontpart of the body being shown in section taken below the seat in order tobetter illustrate the manipulating devices. Fig. 3 is a central sectiontaken through the same with the parts shown in showing the members inthe dumping position but with the central dumping member centrallysupported, its hinged parts being folded downwardly to discharge part ofthe load in front and part in the rear. Fig. 5 is a front end elevationof my improved.

dumping vehicle. Fig. 6 is a section'taken on the line 6-6 Fig. 4.looking toward the rear or in the direction indicated by the arrow; Fig.7 is an enlarged detail View of the mechanism for manipulating thedumping members. F ig. .8 illustrates the same construction as Fig. 7viewed in the direction at right angles to F ig. 7 Fig. 9 is an enlargeddetail view illustrating'the cam lever employed in locking the manipu-Fig. 10 is, a view similar to cam in a difierent position. Fig. 12 is across section similar to Fig. 6 but showing the central dumping sectionin place and 1n position to dump the load at one side of the vehicle.Fig. 13 is a fragmentary section of the same but with the centraldumping member raised to the closing horizontal posiftion.v Fig. 14 isan end view of the adjust-- .able walls located at the opposite ends ofthe central dumping section their function being ..to prevent thematerial to be dumped at either side of the vehicle from escaping ineither the rearward or forward direction.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the frame work of the vehicle which ismounted upon wheels 6. 'Upon this frame work of the vehicle body aremounted two end dumping -members 7 and 7 each of which is hinged at 8and whose extremities remote from the these devices will be su The leveris loosely mounted on the drum asshown at 14 and may be employed to turnthe drum in either direction according to the position of the pawl 12.This dog may be made to engage the ratchet or toothed wheel 10 on eitherside of the lever and its position will determine the movement of thedrum for a given movement of the lever arm. The pawl is easily shiftedfrom one position to the other by operating a small arm 15 which isconnected with the bolt or pin 16 which secures the pawl to the lever.Upon the hand lever is also fulcrumed a spring-actuated device 17pivotally connected with the lever as shown at 18 and having a coilspring 19 acting upon one extremity thereof and forcing the otherextremity downwardly upon the pawl 12 whereby the latter is caused tomaintain any desired position of adjustment.

The hinge member 7 has two chains or other suitable flexible devices 20connected with its forward extremity as shown at 21. These chains passupwardly over pulleys 22 carried by a shaft 23 mounted upon therelatively stationary frame work of the vehicle. Another flexible device24 is secured to and passes around the drum on each side ofthe vehicle,its opposite extremity being connected with a central dumping member 26-as shown at 24 while a branch flexible device 28 leading from the mainflexible device 24, passes downwardly and is connected with the oppositeside of the central dumping device as shown at 29. Still anotherflexible device 25 is connected at one extremity with the drum 9 and atits opposite extremity to a rod 56 slidable in guides 27 mounted on theframe work. As the flexible devices'and their connections are the sameon each side of the vehicle a descri tion of one set of cient for both.The chain 24 is supported by a guide pulley 30 located on the upper partof the frame work; while the chain 28 is supported by a similar guidepulley 31.

Connected with the rod 56 at its rear extremity as shown at 32 is aflexible device 33 which passes over a pulley 34, its rear extremitybeing connected with the rear extremity of the dumping section 7 asshown at 35. The chain 24 on each side of the vehicle, passes through ashoe 36 in which is pivotally mounted a cam 37 with which is connectedan operating arm 37 When it is desired to support the central dumpingmember on one side of the vehicle to allow its other side to tiltdownwardly to the dumping position simultaneously with the assumption ofthe dumping position by the end dumping members, the cam lever is forcedto the locking position or that indicated in Fig. 9, whereby the chain24 on one side is locked in the shoe. Then as the drum 9 is rotated tooperate the dumping members 7 and 7 the chains 24 and 28 on one side ofthe vehicle are not slackened while those on the other side areslackened to allow the central dumping member 26 to move downwardly tothe position indicated by dotted lines in Fig. 3.

Attention is called to the fact that there is a locking cam 37 on eachside of the vehicle and when this locking cam is thrown to the positionto prevent the chain or other flexible device 24 from passing throughthe shoe 36, the chains 24 and 28 will be locked I against movement onthat side while corresponding chains on the opposite side will bereleased and allow the corresponding side of the central dumping member26 to. drop downwardly to the dumping position.

In case it is desired to lower the dumping member 26 to the horizontalpositionyor allow bothsides thereof to move downwardly together, the cam37 is thrown to the osition shown in Fig. 11 on both sides 0 thevehicle. In this event, by the proper ma nipulation of the drum 9, thetwo dumping members 7 and 7 A will be tilted to the dumping positionwhile the central dumping member 26 will be lowered in the horizontalposition.

In order to provide suitable walls at the opposite ends of the centraldumping space, so that as the central dumping member is lowered, thematerial can neither fall forwardly or rearwardly but must pass to thedesired side of the vehicle, and'at the same time not'allow these wallsto project downwardly so far as to be in the way when the members arenot in the dumping position, I employ at each end of this centraldumping space two members 38 and 39 which when the dumping members arein the raised position, overlap each other as shown in Fig. 1 and at thesame time are carried upwardly with the dumping member 26 by virtue ofthe fact that the said overlapping walls are provided with inwardlyprojecting lips 38 and 39*, respectively. These overlapping walls 38 and39 are both connected with the stationary frame work of the vehicle, ateach end of the central dumping space bypins 40 passing through verticalslots 41 formed in the central portion of the wall members. The pins 40are provided with heads which moves downwardly. 'ing member m'ovesdownwardly on one side from above.

overlap the inner member 38 at each end of the space and prevent themembers 38 and 39 from-slipping ofi the pins. At the same time thesemembers slide freely on the pins during the raising and lowering of thecentral dumping member. The inner wall members 38 located at theopposite ends of the central dumping space, are connected at each sideof the vehicle by a bar 42 which the central dumping member 26 engagesas it As the central dumpof the vehicle, the two overlapping walls 38and 39 move downwardly together, until the lip 43 on each member 39engages a projection 44 on the stationary part of the frame work. Afterthis occurs the members 39 cease to move downwardly, but the members 38continue their downward movement by virtue of the pressure of the member26 The members 38 are then allowed to move downwardly until the upperextremities of their slots 41 engage the pins 40. This range of movementis so regulated, as to allow the wall members 38 to move downwardly asufficient distance to harmonize with the dumping position of thecentral dumping member 26. By virtue of the inwardly projecting lips 38and 39 of the movable side walls, these walls are restored to theirraised position as the dumping member 26 is carried upwardly in a mannerthat will be readily understood.

In order to permit the central dumping member to allow the load to falldirectly underneath the vehicle, I divide the member 26 into two parts26 and 26 these two parts being connected by hinge pins 45. When it isdesired to cause the parts of the member 26 to move on their hinge pins45, whereby each part is allowed to fall downwardly as shown in Fig. 4,the hinge pin 45 on each side of the vehicle is suspended by a link 46which is passed upwardly through a beam 47, its upper extremity engaginga removable pin 48 inserted in the central stationary frame part 49 ofthe structure.

Attention is called to the fact that the vehicle is provided on eachside of its central part with closed stationary members 49 which confinethe central portion of the load at the sides when the central dumpingmemher is in the raised or closed position. Now assuming that the hingepins 45 are suspended by the links 46, if the shaft 9 is manipulated torelease the flexible devices 24 and 28 on opposite sides of the vehicle,the two parts 26 and 26 will fall downwardly to the position shown inFig. 4 allowing the load to dump immediately beneath the vehicle, partof it toward the front and part toward the rear. In this event the parts26 and 26 of the central dumping member leave the lips 38 and 39 of themovable walls. But when the parts of the central normal position, theyrengage the lips 38 and 39 and lift the movable wall parts to theirnormal position.

From the foregoing description the use and operation of my improveddumping vehicle will be readily understood. Assuming that it is desiredto dump the load to either side .of the vehicle, the cam lever 37 isthrown to the position shown in Fig. 9, on the opposite side of thevehicle whereby the flexible device 24 is prevented from passing throughthe shoe 36 on that side. Then as the shaft 9 is properly manipulated,the flexible devices 24, 25 and 28, the rod 56 and the flexible devices20, are operated to throw the dumping members 7, 7 and 26 to the dumpingposition. It will be understood that by virtue of the fact that theflexible the opposite side the corresponding flexible device will runthrough the shoe and allow the central dumping member to move downwardlyon that side. When, however, the suspension links 46 are connected withthe hinge pins 45 of the central dumping member, the cam levers 37 mustbe released on both sides of the vehicle, so that the chains 24 areallowed to run through their shoes 36 as will be readily understood,from an in spection of the drawing, reference being made particularly toFig. 4.
